HENRY CARL ADAM, OF HAMILTON, AND JACOB CHRISTOPHER ADAM, OF TRENTON, ONTARIO, CANADA.

SCOTCE.

AppIication filed June 1, 1314.

To all whom it may concern:

Be it known that we, HENRY CARL ADAM,

f the city of Hamilton, in the county of Ventworth, in the Province of Ontario, Canada, and JACOB CHRISTOPHER ADAM, of the town of Trenton, in the county of Hastings, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Sootches, of which the following is the specification.

Our invention relates to improvements in scotches, and the object of the invention is to devise a scotch with a removable blade which can be readily inserted into the handle portion and easily removed therefrom.

A further object is to construct a scotch in which the blade can be reversed when required.

Our invention consists of a handle portion having a hollow head, a blade extending through said head and provided with a series of serrations on the upper and lower faces thereof, a toothed eccentric suitably journaled in the hollow handle and adapted to engage serrations on the lower side of the blade, a lever extending out from the eccentric, and a spring secured at one end to the lever and at the other end to the handle of the scotch, the pivoted eccentric being normally retained in the engaged position, all as hereinafter more particularly described and illustrated in the accompanying drawings in which Figure 1 represents a side view of a scotch constructed according to our invention. Fig. 2 is an enlarged cross sectional, view showing the head of the handle, a portion of the blade and the disposition of the eccentric. Fig. 3 is an enlarged view of the head taken at right angles to Fig. 1. Fig. c'is a plan view of one of the blades used in the scotch constructed according to our invention, and Fig. 5 is a similar view of another blade.

Like characters of reference indicate cor responding parts in the different views.

1 is the handle of the scotch, and 2 the hollow head thereof, the top of said head being inclined.

3 is a toothed eccentric suitably journaled to the head 2 by the pin 4, said pin having a lever end 5 and the other end of the pin 4: being threaded and carrying a nut 6 counter-sunk into the head 2.

7 is a blade for the scotch having an up- Specifieation of Letters Patent.

Patented Aug. 10, 1915.

Serial No. 242,329.

per and lower serrated portion 8, the teeth of the eccentric 3 engaging the serrations on the lower side.

9 is a lever extending from the eccentric.

10 is a spring connected at one end to the lever and at the other end to the head of the handle 2.

The blade is applied as follows :The lever 9 is turned upwardly until there is suflicient space between the eccentric 3 and the head 2 of the handle to insert the blade. The blade is then inserted until the serrations are over the eccentric when the lever is sprung downwardly under the action of the spring and the teeth of the eccentric engage the lower serrations effectually holding the blade in position. It is to be understood that the upper edge of the blade bears against the head 2. To remove the blade it is only necessary to push up the end of the lever again when the eccentric will clear the blade and allow its removal. Further the lever end 5 of the pin 4. is adapted to engage the side of the head 2 of the handle and thus prevent the pin from being displaced.

From the above description it will be seen that a scotch constructed according to our invention can have its blade readily removed as above described. Further the blade can be turned over when one edge of the chiseled end is worn, or the blade can be reversed so that the pointed end is in the desired position, or a blade having a pointed end and a toothed end, as shown in Fig. 5, can be used in place of the blade shown in Fig. 4.

vVhat we claim as our invention and de sire to secure by Letters Patent is 1. In a scotch, the combination with the handle having a hollow head, of a blade inserted into the hollow head and having a serrated lower face, a toothed eccentricjournaled in the head of the handle, a lever extending outwardly from the eccentric, and a spring connected at one end to the lever and at the other end to the handle.

2. In a scotch, the combination with the handle having a hollow head, of a blade inserted into the hollow head and having a serrated lower face, a toothed eccentric in the hollow head, a pin loosely extending through the eccentric, a nut threaded on one end of the pin counter-sunk into the hollow head, the other end being turned over and adapted to engage the side of the handle, the toothed portion of said eccentric engaging the serrations on the lower face of the blade, a lever extending out- Wardly from the eccentric, and a spring connected at one end to the lever and at the other end to the handle.

In testimony whereof, We have signed at the city of Hamilton, in the county of \Ventthis 29th day of May, 1914.
